Content marketing is full of ghostwriters, producing professionally written content under someone else’s byline. However, I’ve encountered a lot of confusion over how ghostwriting should work and where lines should be drawn or credit given.

Crikey, marketers and publishers can be slow on the uptake sometimes. Advertising revenue has been declining for decades, leading many to predict the long and painful death of traditional media business models. Add to this the rapid increase of ‘banner blindness’—as skeptical website visitors filter out display advertising by either ignoring it or using an ad blocker—and publishers have found themselves at war with their own readerships.

Think being a content marketer is tough? Try convincing an entire nation! Anyone fighting to gain or retain the White House needs to know a thing or two about getting a message across in the most persuasive way possible. And with a relentless news cycle in print, television and radio, plus the newer channels of social, email, apps and more, the choice of media can have a massive impact on that message.

Content marketers often rely on numbers to convey information and motivate consumers: web pages devoted to lengthy tables of technical specifications; white papers packed with charts and graphs; blog articles that reduce complex topics to lists of statistics. And there’s no doubt that such data-rich content can work—to a point. However, numbers aren’t nearly as persuasive, nor as easily understood, as we would like to believe.

Finding a good writer who is also an expert on a niche or highly technical industry topic—and who is also available to write for you at an affordable rate—can be like hunting the proverbial unicorn. Yet the very exclusivity of those skills is what makes the hunt worthwhile.
